| Ssliasil said: Ignore the GPU and focus specifically on sending graphics and sound data singularly through the Cell and you can make an amazing game (killzone and Uncharted for example) The Cell (which is one of the worlds best CPU and GPU) doesnt cooperate/communicate with the PS3's Main GPU all that well. Uncharted 2 unlocked half the power of the Cell by completely ignoring the main GPU, and Exclusives havent looked back since. BTW bet on the PS4 having one 16-Core Cell Processor and one 8-Core Cell Processor. The 8-core being the mainstay GPU and the 16-core as the CPU. Expect 4 cores of the 16-core Cell to be used as mainstay Security, and one for the XMB2.
Leaving 11 Cores for general processes and 8 cores for Graphic rediculousness. Scoop. |
Actually Uncharted 2 uses the GPU in the PS3 extensively they just off load post processing to the CELL to free up the GPU to do other things faster.
" In the case of Uncharted 2, post-processing techniques such as the game's phenomenal depth-of-field effect (pretty much the best seen on console to date) are hived off to the SPUs. It's an intriguing way of using resources. Presumably the GPU would be able to carry out the same task a lot faster, but if the RSX is otherwise engaged in a computationally more expensive task, it just makes more sense to use the SPUs to do the same job."

God of war 3 is the same they off loaded post processing and Anti-Aliasing which allowed them to use Morphological Anti-Aliasing but every other graphics task is still done on the GPU because it's better at them than the CELL. Offloading tasks makes games look and perform better by letting the GPU do what it does well without worrying about certain tasks. No game on the PS3 doesn't use the GPU and any that did would look or perform like shit...
